V2X: Preserving the Future of Connected Vehicle Technology

​​​​​​​​​ ​​​​​​​


​​What is Connected-Vehicle Technology?

Connected-vehicle technology enables commercial and passenger vehicles to communicate with each other, with the infrastructure, and with other road vehicles, such as motorcycles. It is also described as vehicle to everything (V2X), an umbrella term covering the various elements with which vehicles can communicate.

Connected-vehicle technology (V2X): Where are we today and what does the future look like?

In our four-part Most Wanted List (MWL) Interview video series, Board Member Michael Graham talks with experts from government, industry, and academia about the safety benefits and the maturity level of V2X technology, the reasons for its scarce deployment, and the impact of the Federal Communications Commission’s (FCC) recent actions to limit the spectrum available for transportation safety.

  • The basic viability of V2X is being threatened. 
  • The FCC’s regulatory actions substantially limit the spectrum available for transportation safety and allow for harmful interference from unlicensed Wi-Fi devices. 
  • Regulatory uncertainty is the primary reason for the lack of V2X deployment.

Require Collision-Avoidance and Connected-Vehicle Technologies on all Vehicles​ is a safety topic on our MWL of Transportation Safety Improvements.

We can no longer afford to wait; we need to move toward the nationwide deployment of this technology to save lives and prevent injuries. 

Series Episodes:​

Episode 1: V2X Overview, Effectiveness Research, and Wi-Fi Interference ​

​We examine the maturity level of the technology, the impact of the FCC’s decision to substantially reduce the spectrum, and National Highway Traffic Safety Administration’s research examining the impact of interference of unlicensed WiFi devices on V2X communication.
